SBR20LUU linear slider

⚙️Product Features:

Lengthened Dual-Bearing Core: Built-in dual linear bearings inside a single longer block dramatically increase load capacity and tracking stability compared to standard SBR20UU blocks.
Premium Aluminum Housing: The CNC-machined aluminum alloy case offers excellent strength, a lightweight profile, and superior industrial corrosion resistance.
Open-Type Configuration: Perfectly matches SBR20 supported cylindrical guide rails, effectively preventing rail deflection or bending under heavy weight.
Smooth & Low-Noise Travel: High-grade steel balls paired with optimized industrial nylon retainers ensure low friction, reduced noise, and ultra-precise linear positioning.
Flexible Brand Procurement: Gain a competitive edge with our factory-direct RMO brand, or utilize our global trading network to source major international bearing brands.

⚙️Product Application:

Thanks to its heavy-load capacity, extended length, and open-type design, the SBR20LUU slider is widely utilized in:

CNC routers, DIY laser engravers, and plasma cutting machine axes.
Large-scale 3D printers and industrial additive manufacturing systems.
Automated assembly lines, factory pick-and-place robotics, and sorting systems.
Precision woodworking machinery and stone cutting equipment.
Linear guide stages, laboratory testing rigs, and material handling systems.

⚙️Precautions:

1. Keep clean	2. Use with caution	3. appropriate tool	4. Hot-loading	5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.	Strong impact during use can easily cause scratches and indentations.	Avoid replacing existing tools, and use appropriate tools.	Bearings are precision parts, so hot installation is recommended.	Sweat on your hands during operation will cause rust, so it is best to wear gloves.
